The backpack is comfortable enough. The only gripe is the torso strap isn't actually long enough to be usable, and I don't have a big torso (42 chest, 34 waist). I've worn it for about an hour on my motorcycle. With the bag full and my large laptop in it, my shoulders did feel a bit like pressure points might be getting pushed on but I never had any issues (numbness, etc.). I could probably loosen the straps a bit but I prefer bags to be snug when riding so could be a personal issue.
The bag holds my 17.3" MSI laptop fine, just have to pop the top over the corners after sliding it in. Anything smaller shouldn't have any issue. The mesh pocket in the front of the same section holds the fairly bulky power cord for it.
The middle section is big enough to hold a mouse, my Sony sound-cancelling headphones in their case, a travel power strip, a solar phone charger (in case), and some other random cables (phone charger if needed, etc.). The pockets in it are useful for small items but I don't use them all.
The little pocket on the top front of the outside I figure will be good to hold my phone, a passport, etc. while travelling if needed.
The pocket inside after undoing the clip has some space, but if you have the middle area full of enough items then there won't be much room left in this one. I currently just have a couple of DVDs in there to watch on the go.
The front zip pocket under the clip holds the small screwdriver I use for laptop tasks, a small flashlight, USB drive(s) if not stored in a middle section pocket, pen(s), and whatever other smaller items.
I like that it has the sleeve to slide the bag over a suitcase handle behind the shoulder straps, although I haven't tried it for fit when the bag is full. It might get snug.
Padding on the bottom might not be as plentiful as some others, but there is a stretch of material over the bottom to at least help make it water resistant if not waterproof. There is some padding around the computer sleeve. So long as it's not thrown around I figure it should protect the computer well enough.
The interior material is yellow. Not a selling point for me but I guess it should help find items in the bottom.
The patch it comes with I guess is 'cute' marketing, although I'll be changing it for something else. The bag itself does look a bit tactical, although just in general. The few Molle-type bits probably wouldn't be too useful but I'm sure they could be used for something. There is a bottle holder-type pocket on the outside on each side. They don't look like they'd hold a large bottle but I haven't tried them yet. There are also a couple of pen pockets on the outside on one side.
The bag isn't as roomy as some others, but that means it's also not as bulky (especially if full). It seems fairly streamlined, and would probably do well for travelling. I reckon it should fit under a plane seat, but haven't tried (might find out in a few weeks). It should certainly fit in about any overhead bin. The only downside there is it's not TSA compliant so the laptop has to come out at security. They probably could've made it fold down in the back, but guess they figured the mesh water bottle pockets and a couple more pen holders were a better feature as those prevent the zippers from going more than halfway down either side.
It has compression straps on the bottom sides, but those are probably more for looks than use since there aren't any on the top.
No issues yet with the carry strap, or the shoulder strap connections. The carry strap has tabs on the side (such as one bag I have uses to un-velcro a couple water hose openings) but they're just for decoration that I can tell.
Overall the bag so far seems pretty well put together and is useful. It might have a couple of points I'd prefer be better (or there at all) but I knew about those by & large before getting it by reading the description and looking at the pictures. For the price it's a pretty good laptop bag that should fit all laptops except maybe extra bulky/thick ones.
